Hole doping and weak quenched disorder effects on the 1D Kondo lattice for ferromagnetic Kondo couplings [PDF]

open access: yesarXiv, 1997
We investigate the one-dimensional Kondo lattice model (1D KLM) for ferromagnetic Kondo couplings, by using the bosonization method. The ferromagnet ic 2-leg spin ladder and the S=1 antiferromagnet occur as new one-dimensional Kondo insulators, for a half-filled band.

Gate‐Tunable Exchange Bias and Voltage‐Controlled Magnetization Switching in a van der Waals Ferromagnet

open access: yesAdvanced Materials Interfaces, EarlyView.
Their research explores van der Waals magnets and uses a perpendicularly magnetized FGT/O‐FGT/hBN heterostructure to demonstrate gate voltage‐controlled magnetization switching. They observe bidirectional voltage control of exchange bias (EB), with the highest EB magnitude of 1.4 kOe and a blocking temperature of 150 K, both among the highest for ...

Structural and electronic properties of Eu- and Pd-doped ZnO

open access: yesNanoscale Research Letters, 2011
Doping ZnO with rare earth and 4d transition elements is a popular technique to manipulate the optical properties of ZnO systems. These systems may also possess intrinsic ferromagnetism due to their magnetic moment borne on 4f and 4d electrons.

A ferromagnetic inequality

open access: yesJournal of Combinatorial Theory, 1969
AbstractThe investigation of the monotonicity of correlation as a function on interaction in Ising ferromagnets with integral spin led to the inequality on subgroups and cosets. The mathematics seems similar to that arising in error-correcting codes.

Tailoring of Creep Regime Domain Wall Dynamics in Perpendicularly Magnetized Pd/Co/Pd Trilayers

open access: yesAdvanced Materials Interfaces, EarlyView.
Understanding magnetic domain wall (DW) dynamics is vital for improving the performance of heavy‐metal/ferromagnet‐based spintronic devices. This work manifests a fundamental investigation encompassing structural properties and magnetic DW motion in Pd/Co/Pd multilayers having perpendicular magnetic anisotropy.

d° Ferromagnetism of Magnesium Oxide

open access: yes, 2017
Magnetism without d-orbital electrons seems to be unrealistic; however, recent observations of magnetism in non-magnetic oxides, such as ZnO, HfO2, and MgO, have opened new avenues in the field of magnetism.
